Missing Alaska Family Stumps Police, FBI

After three weeks of searching, investigators are still clueless as to what happened to an Alaska family last seen in late May. A canine scent detection team, along with additional aerial and ground crew, has scoured the area—their town of Kenai is 65 miles southwest of Anchorage with a population of 7,100—for any sign of 22-year-old Rebecca Adams; her daughters, 5-year-old Michelle Hundley and 3-year-old Jaracca Hundley; her boyfriend, 37-year-old Brandon Jividen; and their dog. The trail is so cold that authorities have called off the dogs and reduced the ground search, reports the Alaska Dispatch.

"It's a mystery," Kenai police chief Gus Sandahl tells People. "But finding them is definitely the highest priority of our department," which has been working with Anchorage-based FBI officials. Police add that there were no signs of forced entry into the family’s apartment, which was locked, nor were there signs of a struggle or obvious foul play. Adding to the mystery, both Adams' and Jividen's cars are parked outside; Adams' wallet, cell phone, and bank card were in the apartment; and their camping gear was left behind. They also didn't pay their rent, notes Reuters. Adams' sister, Lanell Adams, says the two last spoke on May 27 and that her sister sounded “distressed,” per KTUU. (Another mother and her child have vanished, but police think they know why.)
